Job summary

QuTwo in Finland seeks a Senior Infrastructure Architect who is a hands-on builder to design, deploy, and run the GPU infrastructure behind our AI platform — someone who has actually racked the servers, cabled the fabric, brought the cluster online, and locked it down.

You will plan and execute GPU data center build-outs, design high‑performance compute fabrics, own capacity planning with partners, and build the software layer for provisioning, firmware, monitoring, and scheduling while

Qualifications

• Proven hands-on GPU/HPC data center deployment experience.
• Experience rack‑level design, cabling, power, cooling.
• Strong networking with InfiniBand/Ethernet.
• Security familiarity with ISO 27001, SOC 2 or Katakri criteria.
• Fluent English; Finnish a plus; willingness to travel.

Responsibilities

• Plan end-to-end GPU data center builds: rack/power design, cooling, cabling, deployment.
• Design high-performance compute fabrics (InfiniBand/RoCE), storage, and out-of-band management for large GPU clusters.
• Own capacity, power, and cooling planning with partners and site operators.
• Build software layer for provisioning, firmware/drivers, monitoring, and scheduling.
• Embed security from day one: access controls, network segmentation, tamper‑evident logging, EU data residency compliance.

Job description

About Qutwo

QuTwo is a Finnish AI company building sovereign AI solutions for Europe. Our platform, QuTwo OS, orchestrates workloads across classical systems, AI accelerators, and emerging quantum hardware — giving enterprises high-performance AI on infrastructure they control.

We are looking for Senior Infrastructure Architect who is a hands‑on builder to design, deploy, and run the GPU infrastructure behind our AI platform - someone who has actually racked the servers, cabled the fabric, brought the cluster online, and locked it down

What you will do

• Plan and execute GPU data center build-outs end to end: rack and power design, high-density cooling, cabling, and physical deployment of GPU servers and networking.

• Design and stand up high-performance compute fabrics (InfiniBand / RoCE), storage, and out-of-band management for large GPU clusters.

• Own capacity, power, and cooling planning together with colocation partners and site operators.

• Build the software layer that makes the metal usable: provisioning, firmware and driver lifecycle, monitoring, and cluster scheduling.

• Bake security in from day one: physical access controls, network segmentation, hardened baselines, key and secrets management, tamper‑evident logging.

• Ensure our infrastructure meets the security and compliance requirements our customers demand — including EU data residency and sovereignty expectations, ISO 27001‑aligned controls, and customer security audits.

• Provide operational support and troubleshooting.

What we are looking for

• Proven, hands‑on experience setting up GPU or HPC data center environments — you have physically built and commissioned clusters, not just operated them.

• Strong grasp of data center fundamentals: power distribution, UPS, cooling (air and liquid), rack density, and site selection trade-offs.

• Solid networking skills, including high-speed interconnects (InfiniBand andEthernet) and secure network design.

• Real understanding of security requirements for critical infrastructure: physical security, access management, supply‑chain integrity, and frameworks such as ISO 27001, SOC 2, or Finland’s Katakri criteria.

• Comfort with Linux and automation — you automate what you would otherwise repeat.

• A doer’s temperament: you take ambiguous goals, break them into concrete steps, and deliver without waiting to be told twice.

• Fluent English; Finnish is a plus. Willingness to travel occasionally.

Nice to have

• Experience with NVIDIA DGX/HGX-class systems, liquid‑cooled deployments, or multi‑megawatt sites.

• Background in environments with elevated security requirements (finance, government, defense, or critical infrastructure) or eligibility for security clearance.

• Experience negotiating with colocation providers, utilities, or hardware vendors.
